Sgt. Richard Berns tweeted the heroic photo of the cops saving the trembling dog and captioned it: "This dog was left in this car on the hottest day of the year with no water or ventilation. It has both now."

He explained to one Twitter user: "I smashed the rear window (away from the dog) and the owner will pay for the damage."

According to ITV, the car's owner returned to find the windows shattered and was given stern words of advice by the police.

Officers then contacted the RSPCA who were made aware of the situation.

The animal welfare charity have reportedly made a home visit to the owner since the incident.
